Program jumps and deletion blocks
2.2 Deletion blocks
There is a further way of optionally including or excluding certain parts of
the program by excluding explicitly marked blocks.
The program blocks intended for optional exclusion are marked simply by
a preceding / (slash).
Example: /N200 CYCLE96(24,-30,"A",3)
Simply by activating the option "SKP Skip block" (after pressing the VSK 4
"Prog. Cntrl." (Program control) in the automatic mode) all blocks marked
with a "/" will be ignored by the control unit.
If this option is deactivated, the marked blocks will be executed in the
same manner as all others.
SKP is activated; in the program
mode the blocks with a preceding
slash will be ignored.
Shown on the next page is a possible example for the usage of this way of
program manipulation.
Page 4
SKP is deactivated; the control
also executes the blocks with a
preceding slash.
